Mix the flax and water together and let stand for around 10 minutes or until gelatinous while you get on with the rest of the recipe

Preheat the oven to gas 5 / 170C / 325F and grab a foil tin - one like you'd get from the Chinese Takeaway as shown

Gently melt the butter, sugar and syrup together in a small saucepan then take off the heat

Whisk the flour, cocoa and baking powder together then add to the pan and stir in

Add in the flax mixture and vanilla, stir, then fold in the chocolate chips

Scrape into the small foil tray and bake for 15 - 20 minutes or until the top has set and the brownie edges are pulling away from the sides of the tray

Let stand in the tray on a wire rack for 20 minutes then cut in half and serve
